Make sure that your connections are all ok, red stripe at pin 1, and all master and slave jumpers are correct. This

When you got to look at properties when they have the "!" by them, what does it say? device conflict? resource problem?

this is what it says in properties on both of them

"Your registry might be corrupted. (Code 19)"

im running w2k pro....

arrr stupid thing....

think it can be fixed without a format???
